20130062264 | SORTING MINED MATERIAL - A method of sorting mined material, such as mined ore, is disclosed. The method comprises exposing particles of mined material to radio frequency electromagnetic radiation and heating particles depending on the minerals present in the particles and then thermally analysing particles exposed to radio frequency electromagnetic radiation to detect temperature differences between particles which indicate differences in the minerals in the particles. The method also comprises sorting the particles on the basis of the results of the thermal analysis. | 03-14-2013 |
20130186992 | SORTING MINED MATERIAL - An apparatus for sorting mined material, such as mined ore, includes an applicator for exposing fragments of a material to electromagnetic radiation and an assembly for distributing fragments from the applicator so that the fragments move downwardly and outwardly from an upper inlet of the assembly and are discharged from a lower outlet of the assembly as individual, separate fragments that are not in contact with each other. The apparatus also includes a detection and assessment system for detecting and assessing one or more than one characteristic of the fragments and a sorting means in the form of a separator for separating the fragments into multiple streams in response to the assessment. | 07-25-2013 |
20140260802 | PROCESSING MINED MATERIAL - An apparatus for processing mined material, such as mined ore, is disclosed. The apparatus includes an applicator ( | 09-18-2014 |
20140291212 | MICROWAVE APPLICATOR - A microwave radiation applicator for exposing mined material to microwave radiation is disclosed. The applicator includes side walls | 10-02-2014 |
20140322106 | METHOD FOR THE TREATMENT OF ORE MATERIAL - A method for treating an ore material with electro-magnetic energy, the method comprising at least the steps of: agglomerating the ore material; irradiating the ore material with electromagnetic energy; thereby heating the liquid in the ore material; vapourising at least a portion of the liquid in the ore material; forming micro-channels in the ore material, and acid leaching the ore material. | 10-30-2014 |
20140346091 | PROCESSING MINED MATERIAL - An apparatus for processing mined material that includes an applicator assembly ( | 11-27-2014 |
20150292056 | APPARATUS AND A METHOD FOR TREATMENT OF MINED MATERIAL WITH ELECTROMAGNETIC RADIATION - The present disclosure provides an apparatus for treatment of mined material. The apparatus comprises a source for generating electromagnetic radiation and a microwave inlet region for exposing fragments of the mined material to the electromagnetic radiation. Further, the apparatus comprises a reflective structure adjacent the microwave inlet region and providing, or surrounding, a passage for guiding the fragments of the mined material to the microwave inlet region. The reflective structure is arranged to attenuate penetration of the electromagnetic radiation from the microwave inlet region into the passage during throughput of the fragments of the mined material. | 10-15-2015 |
20150314332 | SORTING MINED MATERIAL - A method of sorting fragments of mined material that includes valuable and non-valuable materials is disclosed. The method comprising heating the fragments by heating selected materials within the fragments and thermally analysing fragments of the mined material to determine the temperature of each fragment. The method further comprises sorting fragments on the basis of the thermal analysis to separate fragments having a temperature within a temperature band defined by a range between an upper temperature limit and a lower temperature limit from fragments having a temperature outside the temperature band. The upper and lower temperature limits are selected to identify fragments as containing an amount of valuable material that is economically viable to extract based on the fragment temperature. Also disclosed are an apparatus for sorting mined material and a method of recovering valuable material by sorting in according with the sorting method. | 11-05-2015 |
